Instructions:
- Leave whole. Dip in boiling water 30 seconds or more to break skins. Plunge in ice water to stop cooking. Drain on paper towels.
- Preheat dehydrator following manufacturer instructions.
- Arrange prepared food on drying trays, leaving small spaces between pieces for good air circulation.
- Stir small pieces to ensure even drying. Rotate trays if recommended by dehydrator manufacturer.
- Check for dryness at the end of the minimum drying time, and then more frequently as drying progresses. Estimated drying time is 12 to 20 hours. Let a sample piece cool to room temperature before testing. Grapes are dry when they are tacky, but don't stick to each other.
- Condition foods before storing.
- Because there is still moisture left in dried fruit. Put in an air tight container and shake well each day to redistribute the moisture for 7 days. If condensation forms inside the container, the fruit needs more drying time.
- Package dried foods in glass jars, food storage containers or plastic food storage bags in small amounts. Store containers in a cool, dark, dry area to maintain quality.
Dry time: 12-20 hours
Test for dryness: Raisin-like, no moist center
